摘要
针对TMS320F2812在信息采集中存在的精度不够,采样值与真实值偏离过大的问题,本文采用了一种ADC校正算法,可以实现对ADC存在的增益误差和偏移误差进行补偿,结合简易的硬件电路,成功实现了对ADC采样精度的补偿。
To solve the problem that TMS320F2812 has a accuracy deviation in data acquisition, even sometimes the sampling value is far from the actual value, a method of ADC correction algorithm is designed, which can realize the compensation in gain deviation and offset deviation. Finally, the compensation of ADC sampling accuracy was completed combining with a simple hardware circuit.
